ABSTRACT

A computer-controlled motorized pump system is provided. A generator is mechanically connected to a power takeoff. A first controller receives AC power from the generator and converts the AC power to DC power and provides DC power to a computing system that has one or more processors and one or more computer-readable hardware storage media and a user interface. A second controller is directly coupled to the first controller and provides AC power to a motor. The motor is mechanically connected to a pump, and the motor is in communication with, or controlled by, the computing system.

TECHNICAL FIELD

The present disclosure relates to a power takeoff pump system. Moreparticularly, the present disclosure relates to a power takeoff pumpsystem for tanker trucks that is controlled through one or morecomputing systems.

BACKGROUND

Freight companies commonly use semi-trailer trucks (more commonlyreferred to as “semi-trucks” or simply “semis”) to transport freight.Often, semi-trucks transport freight in liquid form, pulling one or moretank trailers. Conventionally, pump systems for loading and/or unloadingtank trailers are implemented into semi-trucks used for transportingtank trailers. Implementing the pumps onto the semi-trucks obviates theneed for having on-site pump systems in diverse pick-up and deliverylocations.

A semi-truck pump system is typically driven by a power takeoff (PTO)that is mechanically connected to the semi-truck's transmission toselectively transfer power from the semi-truck's running engine to thepump system. Conventional semi-truck pump systems, however, suffer fromnumerous shortcomings.

In a “wet kit” system, the PTO drives a hydraulic pump that connects toa hydraulic motor for driving a vacuum pump. Wet kit systems are proneto hydraulic leaks, necessitating excessive diagnostics and repairs.Additionally, hydraulic lines in wet kit systems are known to rupturewhen exposed to extreme and/or quickly changing temperatures. Freightcompanies often spend $500 to $1,000 per year in hydraulic motor, pump,and/or hose replacements for each wet kit in their fleet. Furthermore,when a hydraulic line ruptures, a minimum of 5 gallons of fluid spills,which further causes freight companies to incur cleanup expense inaddition to repair/replacement expenses.

Additionally, the performance of the hydraulic pumps and hydraulicmotors of wet kit systems is typically affected by the temperature inwhich the system runs, which can cause the vacuum pump and/or the motorthereof to fail. Wet kits require large cooling systems that can only beplaced on the catwalk between the cab and the fifth wheel plate of thesemi-truck. This arrangement may require that the vacuum pump besuspended over a side of the catwalk, which exposes the vacuum pump todebris impacts that cause additional vacuum pump damage.

Wet kits typically have only a 1,000-hour to 2,000-hour service life byreason of their complexity, user error, and deficiencies in the design.Wet kits can cost freight companies $4,000 or more per year in vacuumpump damages and $10,000 or more per year in downtime losses (per wetkit system in the fleet).

An alternative to a wet kit system is a direct drive system. In a directdrive system, the PTO is attached by a U joint to a driveline that issupported by a carrier bearing. An opposing end of the drivelineconnects, via another U joint, to a gear box that is mechanicallyconnected to the vacuum pump for driving the vacuum pump.

Direct drive systems also suffer from a number of shortcomings. Forinstance, users are often injured by the long, rotating driveline, andthe driveline is susceptible to damage (which in turn may damage the Ujoints, carrier bearing, gear box, and/or vacuum pump). Further,whenever the PTO is engaged, the vacuum pump runs. As a result, if auser fails to disengage the PTO before driving the truck, the excessivetorque exerted on the vacuum pump can lead to its destruction.Additionally, direct drive systems typically have a service life of only3,000 to 4,000 hours and cause $4,000 or more in vacuum pump damages and$6,000 or more per year in downtime losses (per direct drive system inthe fleet).

The complexity of wet kit and direct drive systems makes them prone touser error. Proper operation of a wet kit or direct drive systemrequires careful control and monitoring, and fatigued and/or negligenttruck drivers often fail to exercise due care. For instance, truckdrivers often allow the hydraulic pump of a wet kit to run for excessivetime periods, causing the vacuum pump to overheat. Additionally, truckdrivers often fail to monitor the temperature of pump systems and startvacuum pumps while the pumps have frozen water in them, causing damageto the vacuum pumps. Furthermore, truck drivers often fail to adequatelymonitor pumping operations, which can cause spills that are costly forfreight companies to remedy.

Accordingly, there are number of disadvantages with semi-truck pumpsystems that can be addressed.

The subject matter claimed herein is not limited to embodiments thatsolve any disadvantages or that operate only in environments such asthose described above. Rather, this background is only provided toillustrate one exemplar technology area where some embodiments describedherein may be practiced.

The presently disclosed pump systems may allow vacuum pumps to last upto, or more than, three times as long as they do when implemented on awet kit or direct drive system. Regular maintenance of the components ofwet kits or direct drive systems may be avoided.

In view of the foregoing, the disclosed embodiments may allow freightcompanies to avoid considerable costs associated with repairing andreplacing semi-truck pump equipment and/or remedying spills.

Having just described some of the various benefits and high-levelattributes of the disclosed embodiments, additional detail will beprovided with reference to the Figures, which show various examples,schematics, conceptualizations, and/or supporting illustrationsassociated with the disclosed embodiments.

FIG. 1 illustrates an exemplary schematic diagram of acomputer-controlled power take off (PTO) driven motor system 100. ThePTO 102 may be mechanically connected to the transmission of asemi-truck, such that the PTO 102 is actuated by running the engine ofthe semi-truck. As shown, the PTO 102 is mechanically connected to agenerator 104 so that the generator 104 may be actuated by the PTO 102to generate AC power. FIG. 1 shows the generator 104; however, it willbe appreciated that the generator 104 may be implemented as anelectronic motor that is reversibly operable to receive rotational forceto generate AC power or receive AC power to generate rotational force.In this regard, two motors that are identical may be implemented as thegenerator 104 and a motor 106 for driving the vacuum pump (as describedhereinbelow). In some embodiments, the motors 104, 106 are three-phase,water-cooled, permanent magnet motors (although other motors may beused).

In some instances (as shown in FIG. 1 ), the generator generatesthree-phase AC power (e.g., to maintain a high peak voltage), asrepresented by the W, V, and U wires extending from the generator. Thegenerator provides AC power to a first controller 108, which convertsthe AC power into DC power. In some implementations, the firstcontroller 108 is implemented as a rectifier or another circuit/systemsuitable for converting AC power into DC power. Accordingly, the firstcontroller 108 may provide DC power to one or more computing systems(e.g., electronic control modules (ECMs) shown in FIG. 6 ). In someinstances, one or more computing systems are implemented into the firstcontroller 108 and/or a second controller 110 and are in communicationwith each other and/or with outside computing systems, devices, orcomponents, as represented in FIG. 1 by the CAN Bus Port 112 extendingfrom the first and second controllers 108, 110. It will be appreciatedthat other positionings of the computing system(s) are within the scopeof this disclosure. Further, while multiple controllers are illustrated,it will be appreciated that the components of the various controllersmay be combined into a single controller.

In its most basic configuration, a computing system includes a processorand a computer-readable hardware storage medium that may holdcomputer-executable instructions for execution by the processor. Theprocessor and the computer-readable medium may be combined, such as byusing a microcontroller. A computing system may also include (or are inwired or wireless communication with) a user interface, such as acontroller with one or more input triggers (e.g., buttons, touchscreen(s), etc.). In some implementations, the computing system(s)is(are) in communication (via a wired or wireless connection) with oneor more user interfaces for communicating information to a user and/orreceiving user input. Additional details, functionalities, andconfigurations of the computing system(s) of the present disclosure willbe described in more detail hereinafter with reference to FIGS. 7-9 .

Referring back to FIG. 1 , the first controller 108 is directly coupledto the second controller 110 with two DC coupling wires. The secondcontroller 110 is operable to invert the DC power back into AC power(e.g., three-phase AC power with attendant wiring, as described above)to provide AC power to the motor 106. In some instances, the motor 106is a motor that is identical to the generator 104, although reverselyoperated (i.e., the motor 106 receives AC power and generates rotationalforce, rather than receiving rotational force from the PTO 102 andgenerating AC power).

Because of the DC coupling between the first and second controller 108,110 (e.g., converting from AC power from a generator into DC power, andthen inverting the DC power back into AC power again to power anothermotor), the PTO-driven motorized pump systems of the present disclosuremay be computer-controlled (e.g., by the computing system(s) referred toabove), providing input, monitoring, communication, sensing,notification, and/or safety functionalities that may protect the pumpsystem components, reduce dependence on user attentiveness/care,increase control by administrators (e.g., fleet commanders, freightcompanies), and/or increase the productivity of semi-trucks pulling tanktrailers. By way of example, in some embodiments, the computing systemsof the first and/or second controllers 108, 110 are in communicationwith sensors (e.g., temperature sensors, voltage sensors, pressuresensors, etc.) that are connected to the generator 104 and the motor 106indicated in FIG. 1 by generator sensor cable 105 and motor sensor cable107. Additionally, in some embodiments, the computing systems of thefirst and/or second controllers 108, 110 are configured to be able toselectively activate or deactivate (or otherwise control) the generator104 and the motor 106 (e.g., as indicated in FIG. 1 by encoder cable 109and encoder cable 111). It will be appreciated that the various cablesmay be coupled to one another using standard AMP connectors 113. In someinstances, the computing system(s) within the first and/or secondcontrollers 108, 110 may deactivate the generator 104 or the motor 106in response to user input and/or in response to detecting thattemperatures, voltages, pressures, or other indicators are outside ofoperational ranges. For example, one or more sensors may be coupled toA) the generator 106 via cable 105, B) the motor 106 via cable 107, C)the pump 114 (or its components) via pump sensor cable 115. These andother features associated with the computing system(s) will be describedin more detail with reference to FIGS. 7-9 .

FIG. 1 illustrates that the motor 106 is mechanically connected with apump 114 (e.g., vacuum pump or gear pump), such that the motor 106 isable to drive the pump 114 when the motor 106 receives AC power from thesecond controller 110. When driven by the motor 106, the pump 114 may,for example, load or unload a tank trailer that is connected to the pump114. Accordingly, by using the generator 104 and the motor 106, thePTO-driven motorized pump systems of the present disclosure avoidproblems associated with high-pressure hydraulic lines, hydraulic pumps,hydraulic motors, and drivelines spanning the distance between the PTO102 and the pump 114.

FIGS. 2A and 2B illustrate an example embodiment of the first controller108 implemented on a semi-truck. The first controller 108 (e.g., arectifier or other converter) is wired to receive AC power (e.g.,three-phase AC power) from the generator 104 (FIG. 1 ) connected to thePTO 102 (FIG. 1 ) on the bottom of the semi-truck. The first controller108 converts the AC power received from the generator 104 into DC powerto power one or more computing systems. In the embodiments depicted, thefirst controller 108 is also in communication with one or more sensorsconnected to the generator 104 and configured to provide instructionsto, and receive data from, the generator 104. In the embodiment shown,the first controller 108 includes a CAN bus port connector to connectwith other computing systems. In some instances, the CAN bus portconnector is also connected to the second controller 110 (FIG. 1 ). Inthis regard, the first controller 108 (or a computing system associatedtherewith) may allow for computer control of the generator 104 and/orother portions of the PTO-driven motorized pump system. The firstcontroller 108 is also directly coupled to the second controller 110(FIG. 1 ) via two DC wires to allow the first controller 108 to provideDC power to the second controller 110 (e.g., an inverter). In someembodiments, the first controller and/or the second controller 108, 110may couple to a cooling plate 116 so as to prevent overheating.

As shown, the first controller 108 takes up minimal space and may beinstalled within limited spaces, such as on the steps of the driver'sside of the semi-truck next to truck batteries 117A, 117B, but thoseskilled in the art will recognize that this placement is non-limitingand exemplary only. For instance, in some embodiments, the firstcontroller is positioned proximate to (or implemented as part of) thesecond controller 110, or as part of the generator 104, or within thecab of the semi-truck.

FIG. 3 illustrates an example embodiment of the second controller 110and motor 106 implemented on a semi-truck, the motor actuating a pump114 (best seen in FIG. 4 ). The second controller 110 receives DC powerfrom the first controller 108 via the direct coupling and inverts the DCpower back into AC power (e.g., three-phase AC power) and provides theAC power to the motor 106, which in turn actuates the pump 114.

The second controller 110 is also in communication with one or moresensors (e.g., temperature sensors, voltage sensors, etc.) connected tothe motor 106 via one or more cables (e.g., motor sensor cable 107) andconfigured to provide instructions to and receive data from the motor106, either by using motor sensor cable 107 or encoder cable 111. Inthis regard, the second controller 110 (or a computing system associatedtherewith) may also allow for computer control of the motor 106 and/orother portions of the PTO-driven motorized pump system 100.

As shown, the second controller 110 is installed on the catwalk 119behind the cab of the semi-truck, but it will be recognized that otherplacements are within the scope of this disclosure. For instance, insome embodiments, the second controller 110 is positioned proximate to,or implemented as part of, the first controller 108 or the motor 106,within the cab of the semi-truck, or suspended over a side of thecatwalk.

FIG. 4 illustrates an example embodiment of the pump 114 (e.g., vacuumpump), motor 106 (enclosed in a housing 121 that may be opened usinglatch 123, a cap, or similar mechanism), and second controller 110implemented on a semi-truck 125. The motor 106 is mechanically connectedto the pump 114 to drive the pump 114 using the AC power received fromthe second controller 110. Accordingly, the pump 114 may be connected toa reservoir (e.g., a tank trailer), such as by using hoses 127, 129, toload or unload the reservoir in a manner that is indirectly driven by aPTO while avoiding high-pressure lines, long drive lines, and otherproblems associated with conventional systems for driving a pump with aPTO.

In the embodiment shown in FIG. 4 , the pump 114 is implemented as avacuum pump that is advantageously positioned on the catwalk 119 so asto avoid debris contact that occur when the pump 114 is suspended over aside of the catwalk, as is the typical case with a wet kit or directdrive system. It will be appreciated that other pumps are within thescope of this disclosure (e.g., a gear pump), and the positioning of thepump 114 is not limited to the catwalk 119, as shown. For instance, apump may be implemented as a gear pump or a vacuum pump positioned onthe tank trailer (see, e.g., FIG. 6 ).

It should be noted that the computer-controlled PTO-driven motorizedpump system 100 may include other components (also referred to as “pumpcomponents”) not shown in the schematic diagram of FIG. 1 . For example,FIG. 5 illustrates an example embodiment of a vacuum pump oil reservoir120 and cooling system 122 implemented on a semi-truck 125. The vacuumpump oil reservoir 120 is in fluid communication with the pump 114 toprovide oil to the pump 114 for cooling and/or lubrication. In manyinstances, users negligently allow for the oil reservoir 120 of a pump114 to become exhausted and run the pump 114 without sufficient oil,resulting in costly damage and/or destruction to the pump 114. In FIG. 5, the vacuum pump oil reservoir 120 includes a sensor 131 for detectingthat the oil level is low. The oil reservoir sensor 131 may also be incommunication with a computing system as described herein (e.g.,controller 110), such that a computing system may receive sensor datafrom the vacuum pump oil reservoir sensor 131 and execute commands inresponse to detecting certain sensor readings. For example, if the oilreservoir sensor 131 detects that the oil in the reservoir 120 is belowa predetermined threshold, the controller 110 shuts off power to themotor 106 so that it is not rendered unusable. It will be appreciatedthat the computer system may terminate the power generation for thesystem in more than one location, depending upon configuration. In oneexample, the reservoir sensor 131 is coupled to the first controller108. The first controller 108 may then disconnect the power to theentire system via a contactor or solenoid coupled to, or incorporatedin, the generator 104 or motor 106. If coupled to the generator 104, thecontrollers 108, 110 may use an additional power source, such as truckbatteries 117A, 117B (or other batteries or power sources) to continueto operate even when the generator 104 ceases producing power due to thecontactor terminating the power.

The cooling system 122 of the embodiment shown in FIG. 5 includes aradiator 124 having a fan 126 and is connected to, and in fluidcommunication with, one or both of the generator 104 and the motor 106.As noted above, one or more temperature sensors may be coupled to thegenerator 104 and/or motor 106, and a failure in the cooling system 122may therefore be detected based on the sensed temperatures of thegenerator 104 and/or motor 106. While the cooling system 122 is showncoupled to the motor 106, it will be appreciated that the same coolingsystem 122 or an alternate cooling system may be coupled to thegenerator 104.

As previously mentioned, the pump 114 includes a number of sensorsconnected thereto. Vacuum pump sensors may include, but are not limitedto, pressure sensors, revolutions per minute (RPM) sensors, torquesensors (e.g., for preventing damage caused from running a frozen, dry,or damaged pump), temperature sensors, or other sensors beneficial fordetermining potential failures of the pump. As with the aforementionedvacuum pump oil reservoir sensor 131, these sensors may be incommunication with a computing system (such as first controller 108,second controller 110, or third sensor controller (discussed later))that is configured to receive the sensor data and issue commands tocontrol the motor 106 based on the received sensor data (as describedhereinbelow).

FIG. 6 illustrates the computer-controlled PTO-driven motorized pumpsystem 100 implemented on a semi-truck and tank 128. As shown, the PTO102 is mechanically connected to the generator 104. The generator 104provides AC power (e.g., 3-phase AC power) to a first controller 108(rectifier or other controller/device) for converting the AC power intoDC power. The first controller 108 may include, or be in communicationwith, in some embodiments, an on/off switch 130, digital readouts (e.g.,of barrels or weight, flow rate, etc.), and/or other controls forcontrolling the motorized pump system 100. The first controller 108provides DC power to an electronic control module 132 (“ECM”), which maybe incorporated as part of the second controller 110, or be separatetherefrom (i.e., a standalone control module), and include communicationchannels (e.g., Bluetooth® compatibility, wired connections) forreceiving sensor readings (e.g., from a current or voltage sensor, orPSI gauge to detect the PSI of a hose, or temperature sensor, etc.)and/or commands from user interfaces and/or other computing systems. Thesecond controller 110 inverts the DC power back into AC power (e.g.,3-phase AC power) and provides the AC power to a motor 106 that drivesthe pump 114, which may be implemented as a gear pump or vacuum pump forpumping fluid through a hose hookup. As shown in FIG. 6 , the pump 114may be located under the tank 128 and need not be on the catwalk 119.

In some embodiments, the first controller 108 provides a portion of theDC power to one or more auxiliary batteries (e.g., a battery bank) orother energy storage element for storing energy for use when the dieseltruck engine is not running. In such embodiments, the truck engine maybe off, yet the batteries may supply AC power to the motor 106 via thesecond controller 110 (which inverts the DC power to AC power).Additionally, other truck and trailer components may utilize the powerstored in the auxiliary batteries, such as the climate control system ofthe cab, microwaves, or other driver conveniences (collectively referredto “auxiliary systems”). Additionally, fuel savings may be realized byutilizing the power from the auxiliary batteries. For example, if thevoltage of the batteries exceeds a predetermined threshold, the powermay then be supplied to other components, such as the climate control ofthe semi-truck. By providing power from the auxiliary batteries, it neednot be supplied by the alternator, which reduces the mechanical load onthe engine, thereby increasing fuel efficiency. In other embodiments,power may be provided back to the generator 104 after being inverted,with the generator translating that power into rotational forces backinto the PTO, again improving fuel economy by reducing the mechanicalload on the engine.

Although the particular components shown in FIG. 6 are illustrated incertain positions (e.g., the rectifier 108 is shown as being positionedon the catwalk 119 of the semi-truck, the rectifier 108, ECM 132, motor106, and vacuum pump 114 are all shown as being affixed to variouspositions on the tank trailer 128), it will be appreciated that thesepositionings are illustrative only.

FIG. 7 illustrates a block diagram of a computer-controlled PTO-drivenmotorized pump system 200. While discussed as a separate embodimentusing differing Figure labels, the components and features discussedhereafter may be combined with the features hereinbefore discussed. Tostart the system 200, an ON/OFF switch located in the cab of semi-truck,or any other location, is activated. The computer-controlled PTO-drivensystem includes a PTO 202 mechanically connected to a generator 204 andoperable via a lever or switch. In some embodiments, the PTO 202 engagesand starts the system 200 automatically. Further, in some embodiments,the PTO 202 may be continuously engaged to the generator 204, regardlessof whether a user is using a pump. In a scenario where the PTO iscontinuously engaged to the generator 204, a solenoid 206 (or othersuitable mechanism, such as a contactor), prohibits power fromdistributing through the system to the motor 230 and pump 232 when notin use. In some embodiments, the solenoid 206 is a three-phasedisconnect. In one embodiment, the solenoid 206 is positioned within thehousing of the generator 204 to prevent any live wires exiting thegenerator 204 when the solenoid 206 is disconnected.

However, in some embodiments, with the PTO 202 continuously engaged, thegenerator 204 may send AC power to the rectifier 208. When a user is notusing the motor 230, such as when driving, the rectifier 208 may chargeone or more auxiliary batteries 209. Once the auxiliary batteries 209are above a predetermined threshold, power may then be diverted from theauxiliary batteries 209 to other components (e.g., climate control orback into the PTO 202) to increase fuel efficiency. It will beappreciated that the auxiliary batteries 209 may also receive a chargefrom other sources, such as solar panels 211 or through grid power 213using an electrical outlet and plug (e.g., 220 Volts). In suchembodiments, energy stored in the auxiliary batteries 209 maysignificantly increase the fuel economy of the diesel engine byutilizing that energy for driver comforts, mechanical energy through thegenerator 204 to the PTO, or to run the motor 230 and pump 232 (withoutneed for the diesel engine to run).

Returning to FIG. 7 , the generator 204 provides AC power (e.g., 3-phaseAC power) to a rectifier 208 (or other converter or controller) forconverting the AC power into DC power. The rectifier 208 may be incommunication with a first controller 210, which may be in communicationwith external controls, such as a potentiometer 212 (e.g., 5V variablespeed potentiometer) to manually adjust the speed at which liquid flows,a manual override load switch 214 to start the flow of liquid, a manualoverride unload switch 216 to release liquid from a reservoir tank, andan on/off switch 218. Other digital readouts (e.g., of barrels orweight, flow speed, etc.), and/or other controls for controlling themotorized pump system 200 may be implemented on the external controls(collectively referred to as “external controls”). While therectifier/controller 208 and first controller 210 are shown as separatecomponents, it will be appreciated that they may combined into a singlecontroller unit.

The first controller 210 provides DC power to an electronic controlmodule 220 (ECM) that is in communication with, and monitors, variouscomponents and signals. For example, the ECM is in communication with aload safety pressure switch 222, an unload safety pressure switch 224, aremote control module 226, and a wireless control module 228. Whenpressure in the system exceeds a predetermined threshold (e.g., 25 PSIfor the tank at the load safety pressure switch 222), the ECM controller220 sends a signal to the solenoid 206 to disconnect the power,preventing damage to the truck and system. The remote control module 226may receive communication from a handheld remote, for example, so thatthe system 200 may be controlled remotely, such as while sitting in thecab of a semi-truck or at a distance from the truck. In regard to thewireless control module 228, a smart device (e.g., smartphone) or otheruser input devices with, for example, Bluetooth® may be utilized so asto communicate with the system 200.

The ECM 220 may further receive sensor readings (e.g., from a current orvoltage sensor, PSI gauge to detect the PSI of a hose or tank,temperature sensors, etc.) and/or commands from user interfaces (e.g.,the handheld remote or smart device) and/or other computing systems.These commands ensure the safety of the truck, its components, and theuser, by terminating the pump 232 and/or other components of the system200 when a sensor returns a reading that has been predetermined to beunsafe or undesirable (a triggering event). Additionally, the firstcontroller 210 inverts the DC power back into AC power (e.g., 3-phase ACpower) and provides the AC power to a motor 230 (e.g., a synchronousbrushless induction motor, permanent magnet motor, or other suitablepump motor) that drives a pump 232, which may be implemented as a gearpump or vacuum pump for pumping fluid through a hose hookup.

A cooling system 234 may be in fluid communication with both thegenerator 204 and the motor 230, although they may also have separatecooling systems. One or more temperature sensors may be coupled to thegenerator 204 and/or motor 230, and a failure in the cooling system 234may therefore be detected by the ECM 220 (or first controller 210,depending upon configuration) based on the sensed temperatures of thegenerator 204 or motor 230. It will also be appreciated that while thefirst controller 210 and the ECM controller 220 are shown as separatecomponents, they may be combined into a single component.

FIGS. 8-10 illustrate the aforementioned components of FIG. 7 on asemi-truck 237. The motor 230 is coupled to the pump 232, which may be agear or a vacuum pump. Furthermore, the potentiometer 212 is shown,which may communicate with the first controller 212 and ultimately, theECM controller 220 to control the rate at which liquid flows through thesystem 200. For example, in one embodiment, the potentiometer 212 maycontrol the RPM of the motor 230 and, in a non-limiting example, may beadjusted between 300-900 RPM. It will be appreciated that by controllingthe rate of flow, damage to the system 200 can be avoided while allowinga user to increase or decrease the flow rate. In addition, controllingthe rate of flow can prevent leaks or spills, which can preventenvironmental concerns or costly clean ups.

Referring to FIG. 11 , in some embodiments, the ECM controller 220receives input from a handheld remote 236 FIG. 11 or any other userdevice. The handheld remote may comprise user inputs 238 which maycontrol power, unload, load, and other operations of the system 200.

FIG. 12 illustrates a pressure sensor 240 in communication with the pump232. If pressure exceeds a predetermined threshold (e.g., 25 PSI), theECM 220 sends a signal to the solenoid 206 (or contactor or similarmechanism) to shut-off the system 200, thereby preventing damage. Asdiscussed in earlier embodiments, the ECM 220 may have an alternatepower source so that when the solenoid 206 disengages, the ECM 220 maycontinue to function and monitor the various components in the system200. In one embodiment, the solenoid re-engages and provides power tothe components of the system when the ECM 220 detects, via the pressuresensor 240, that the pressure is between 18 to 25 PSI. It will beappreciated that other sensors may be implemented and monitored by theECM, such as temperature sensors, oil sensors, flow rate sensors, etc.

Referring to FIG. 13 , the cooling system 234 includes a radiator 242and a fan 244 and is connected to and in communication with thegenerator 204 and the motor 230. It will be appreciated that while thegenerator 204 and the motor 230 may both be in communication with thecooling system, the cooling system may be in communication with thegenerator 204 and/or the motor 230. Although the particular componentsshown in FIGS. 8-13 are illustrated in certain positions (e.g., externalcontrols, ECM, motor, and pump are all shown as being affixed to variouspositions on the tank trailer), it will be appreciated that thesepositionings are illustrative only.

FIGS. 14A and 14B illustrate a flowchart representing a computing system300 which may be implemented (e.g., programmed on the ECM 220 or othercontroller) in the computer-controlled PTO-driven motorized pump system100 or 200. The computing system is activated at start 302 (such as whena user toggles a switch in the cab). Once the computing system 300 hasstarted, it checks for a 12 V power supply in step 304. If there is nota power supply, the system 300 returns to the start 302. When it isdetermined that power is present, the system 300 proceeds to step 306.At step 306, it is determined whether the voltage is above apredetermined threshold. If the voltage is above the threshold, then, atstep 308, the contactor (or solenoid, relay, etc.) remains disconnectedor is disconnected, cutting power to the remaining components in thesystem, and the system 300 returns to the start 302. When the voltage isbelow a predetermined threshold, at step 310, the contactor is connectedand the remaining components of the system receive power and areprepared to receive commands. Proceeding to step 312, the unload or loadswitch is pressed (either on a remote, smartphone, or switch on thetruck). After the switch is pressed, the system 300 determines, at step314, if the pressure is above a predetermined threshold. When thepressure is above the threshold, the contactor is disconnected at step316 and the system returns to step 302. If the pressure is below thethreshold, then at step 318 the voltages and variances are checked. Asthe voltages are checked in the computing system 300, it determines atstep 320 whether the voltages are above a predetermined threshold. Ifthe voltages are above the threshold, then at step 322 the contactor isdisconnected.

However, when the voltage is at or below the threshold, at step 324 thetemperature of the motors, rectifier, and controllers is analyzed. Afterstep 324 (shown in FIG. 14A at D1), the system moves to step 326 (shownin FIG. 14B at D2). Once the temperature of the system 300 is analyzedat step 324, it is then determined whether the temperature is above apredetermined threshold at 326. If it is, then at step 328 the contactoris disconnected so as to prevent damage to the system 300, the systemthen returns to step 302 (shown at E2 on FIG. 14B and proceeding to E1on FIG. 14A). When the temperatures are at or below the threshold, thesystem 300 determines whether a signal has been received at step 330.The computing system 300 then determines if the signal is received viaBluetooth® at step 332. If the signal is received via Bluetooth®, thenat step 334 an unload/load command based on the signal is executed andthe system 300 returns to step 314 (shown by C2 on FIG. 14B andproceeding to C1 on FIG. 14A). When the signal is not received byBluetooth®, the system 300 determines whether a signal is received froma remote at step 336. If the signal is from a remote, then at step 338an unload/load command based on the signal is executed and the system300 returns to step 314 (shown by B2 on FIG. 14B and proceeding to B1 onFIG. 14A). If the signal is not received from the remote, then thesystem 300 determines whether the signal is received from a manualswitch. If the signal is from the manual switch, then at step 342 anunload/load command based on the signal is executed and the system 300returns to step 314 (shown by A2 on FIG. 14B and proceeding to A1 onFIG. 14A). However, if a signal is not received via any of thepreviously discussed methods, the system 300 returns to step 330 toverify whether a signal has been received. It will also be appreciatedthat override switches may interrupt any of the foregoing flowchart suchthat the system may be turned on/off, such as switch 218.

FIG. 15 illustrates a schematic representation of a computing system 400implemented in the computer-controlled PTO-driven motorized pump system100, 200, which executes computing system 300. The computing system 400may take different forms, such as electronic control modules (ECMs),personal computers, desktop computers, laptop computers, tablets,handheld devices (e.g., mobile phones, PDAs, pagers),microprocessor-based or programmable consumer electronics,minicomputers, mainframe computers, multi-processor systems, networkPCs, distributed computing systems, datacenters, message centers,routers, switches, and even devices that conventionally have not beenconsidered a computing system, such as wearables (e.g., glasses,head-mounted displays).

As noted, the computing system 400 may also be a distributed system thatincludes one or more connected computing components/devices that are incommunication. Accordingly, the computing system 400 may be embodied inany form and is not limited to any particular embodiment explicitlyshown herein.

In its most basic configuration, the computing system 400 includesvarious components. For example, the computing system 400 includes atleast one hardware processing unit 405 (aka a “processor”), input/output(I/O) interfaces 410, and storage 425.

The storage 425 may be physical system memory, which may be volatile,non-volatile, or some combination of the two. The term “memory” may alsobe used herein to refer to non-volatile mass storage such as physicalstorage media. If the computing system 400 is distributed, theprocessing, memory, and/or storage capability may be distributed aswell. As used herein, the term “executable module,” “executablecomponent,” or even “component” can refer to software objects, routines,or methods that may be executed on the computing system 400. Thedifferent components, modules, engines, and services described hereinmay be implemented as objects or processors that execute on thecomputing system 400 (e.g. as separate threads).

Computer storage media are hardware storage devices, such as RAM, ROM,EEPROM, CD-ROM, solid state drives (SSDs) that are based on RAM, Flashmemory, phase-change memory (PCM), or other types of memory, or otheroptical disk storage, magnetic disk storage or other magnetic storagedevices, or any other medium that can be used to store desired programcode means in the form of computer-executable instructions, data, ordata structures and that can be accessed by a general-purpose orspecial-purpose computer.

The disclosed embodiments may comprise or utilize a special-purpose orgeneral-purpose computer including computer hardware, such as, forexample, one or more processors (such the hardware processing unit 405,which may include one or more central processing units (CPUs), graphicsprocessing units (GPUs) or other processing units) and system memory(such as storage 425). Embodiments also include physical and othercomputer-readable media for carrying or storing computer-executableinstructions and/or data structures. Such computer-readable media can beany available media that can be accessed by a general-purpose orspecial-purpose computer system. Computer-readable media that storecomputer-executable instructions in the form of data are physicalcomputer storage media. Computer-readable media that carrycomputer-executable instructions are transmission media. Thus, by way ofexample and not limitation, the current embodiments can comprise atleast two distinctly different kinds of computer-readable media:computer storage media and transmission media. Additionally, it will beappreciated the components of the computing system 400 may be combined,such as by using a microcontroller, which combines a processor andmemory.

A “network,” like the network 435 shown in FIG. 15 , is defined as oneor more data links and/or data switches that enable the transport ofelectronic data between computer systems, modules, and/or otherelectronic devices. When information is transferred, or provided, over anetwork (either hardwired, wireless, or a combination of hardwired andwireless) to a computer, the computer properly views the connection as atransmission medium. The computing system 400 will include one or morecommunication channels that are used to communicate with the network435. Transmissions media include a network that can be used to carrydata or desired program code means in the form of computer-executableinstructions or in the form of data structures. Further, thesecomputer-executable instructions can be accessed by a general-purpose orspecial-purpose computer. Combinations of the above should also beincluded within the scope of computer-readable media.

Upon reaching various computer system components, program code means inthe form of computer-executable instructions or data structures can betransferred automatically from transmission media to computer storagemedia (or vice versa). For example, computer-executable instructions ordata structures received over a network or data link can be buffered inRAM within a network interface module (e.g., a network interface card or“NIC”) and then eventually transferred to computer system RAM and/or toless volatile computer storage media at a computer system. Thus, itshould be understood that computer storage media can be included incomputer system components that also (or even primarily) utilizetransmission media.

Computer-executable (or computer-interpretable) instructions comprise,for example, instructions that cause a general-purpose computer,special-purpose computer, or special-purpose processing device toperform a certain function or group of functions. Thecomputer-executable instructions may be, for example, binaries,intermediate format instructions such as assembly language, or evensource code.

While not all computing systems require a user interface, in someembodiments, a computing system 400 includes, as part of the I/Ointerfaces 410, a user interface for use in communicating informationto/from a user. The user interface may include output mechanisms as wellas input mechanisms. The principles described herein are not limited tothe precise output mechanisms or input mechanisms as such will depend onthe nature of the device. However, output mechanisms might include, forinstance, speakers, displays, tactile output, projections, holograms,and so forth. Examples of input mechanisms might include, for instance,microphones, touchscreens, controllers, projections, holograms, cameras,keyboards, stylus, mouse, or other pointer input, sensors of any type,and so forth. The computing system 400 may perform certain functions inresponse to detecting certain user input.

The computing system 400 may also be connected (via a wired or wirelessconnection) to external sensors 430 (e.g., a temperature sensorassociated with the generator, motor, or vacuum pump, a vacuum pump oilreservoir sensor, an RPM sensor, a pressure sensor, or other sensors).It will be appreciated that the external sensors may include sensorsystems rather than solely individual sensor apparatuses.

Further, the computing system 400 may also include communicationchannels allowing the computing system 400 to be in wireless (e.g.,Bluetooth®, Wi-Fi®, satellite, infrared, etc.) or wired communicationwith any number or combination of sensors 430, networks 435, and/orother remote systems/devices 440. Remote systems/devices 440 may beconfigured to perform any of the processing described with regard tocomputing system 400. By way of example, a remote system may include anadministrative system that defines operation constraints for thecomputer-controlled PTO-driven motorized pump system 100, 200, receivessensor readings from the sensors 430, and/or issues commands toselectively deactivate the motor/generator that is in communication withthe computing system 400.

Those skilled in the art will appreciate that the embodiments may bepracticed in network computing environments with many types of computersystem configurations. The embodiments may also be practiced indistributed system environments where local and remote computer systemsthat are linked (either by hardwired data links, wireless data links, orby a combination of hardwired and wireless data links) through a networkeach perform tasks (e.g. cloud computing, cloud services and the like).In a distributed system environment, program modules may be located inboth local and remote memory storage devices.

Those skilled in the art will also appreciate that the disclosed methodsmay be practiced in a cloud computing environment. Cloud computingenvironments may be distributed, although this is not required. Whendistributed, cloud computing environments may be distributedinternationally within an organization and/or have components possessedacross multiple organizations. In this description and the followingclaims, “cloud computing” is defined as a model for enabling on-demandnetwork access to a shared pool of configurable computing resources(e.g., networks, servers, storage, applications, and services). Thedefinition of “cloud computing” is not limited to any of the othernumerous advantages that can be obtained from such a model when properlydeployed.

A cloud-computing model can be composed of various characteristics, suchas on-demand self-service, broad network access, resource pooling, rapidelasticity, measured service, and so forth. A cloud-computing model mayalso come in the form of various service models such as, for example,Software as a Service (“SaaS”), Platform as a Service (“PaaS”), andInfrastructure as a Service (“IaaS”). The cloud-computing model may alsobe deployed using different deployment models such as private cloud,community cloud, public cloud, hybrid cloud, and so forth.

Additionally, or alternatively, the functionality described herein canbe performed, at least in part, by one or more hardware logic components(e.g., the hardware processing unit). For example, and withoutlimitation, illustrative types of hardware logic components that can beused include Field-Programmable Gate Arrays (FPGAs), Program-Specific orApplication-Specific Integrated Circuits (ASICs), Program-SpecificStandard Products (ASSPs), System-On-A-Chip Systems (SOCs), ComplexProgrammable Logic Devices (CPLDs), Central Processing Units (CPUs), andother types of programmable hardware.

Having described exemplary components and configurations of a computingsystem 400, the following describes various functionalities that may befacilitated by the computing system 400 or a remote system/device 440 ofa computer-controlled PTO-drive motorized pump system 100, 200 of thepresent disclosure.

In some embodiments, the computing system 400 includescomputer-executable instructions (e.g., stored on storage 425) thatenable the computing system 400 (e.g., by one or more processors 405executing the computer-executable instructions) to selectively activateor deactivate any portion of the motorized pump system, such as thegenerator, the motor, the vacuum pump, etc. In some instances, thecomputing system selectively deactivates at least one component of themotorized pump system in response to a triggering event. In someinstances, the triggering event is detecting that a sensor reading ofone or more sensors 430 has met or exceeded a predetermined thresholdvalue or is outside of a predetermined acceptable range.

For example, the system may selectively deactivate a component of themotorized pump system in response to determining that the oil in thevacuum pump oil reservoir is below an acceptable threshold value. Inanother example, the system may selectively deactivate a component ofthe motorized pump system in response to determining that the pumptemperature has exceeded a predefined safe operation temperature for thepump. In other instances, the system may selectively deactivate acomponent of the motorized pump system in response to determining thatthe RPM of the pump is too high. In yet other instances, the system mayselectively deactivate a component of the motorized pump system inresponse to determining that a predetermined volume of fluid has beenpumped/loaded/unloaded by the pump.

In this way, a computer-controlled PTO-driven motorized pump system ofthe present disclosure may avoid damages caused by driver negligence byallowing for automatic deactivation of the pump system in response toautomatically determining that one or more sensor values have reached alevel that will cause damage to the pump system if the pump continues tooperate (or will cause a spill that will be costly to clean up).

In implementations where the computing system 400 includes or is incommunication with a user interface (e.g., whether directly as an I/Ointerface 410 or as part of a remote system/device 440, such as a mobiledevice of a semi-truck driver or fleet administrator), the computingsystem 400 may receive triggering input (e.g., from an I/O interface 410or a remote system/device 440) that causes the computing system 400 toselectively activate or deactivate one or more components of themotorized pump system (e.g., the motor). For instance, the computingsystem 400 is activated or deactivated by a remote user (e.g., fleetadministration) so as to control the entire system, such as when and howit is activated. Additionally, in some instances, the computing system400 is activated or deactivated depending on GPS location. For example,if a semi-truck is in the desired load/unload location, then thecomputing system 400 may be activated. When the semi-truck is not in thedesired load/unload location, the computing system 400 may bedeactivated.

Furthermore, the computing system 400 may cause sensor values detectedby the various sensors 430 in communication with the computing system400 to be displayed on a user display or user interface (e.g., an I/Ointerface 410 and/or a display of a remote system/device 440). Forexample, FIG. 16 shows exemplary sensor readings being displayed on adisplay of a user/administrator interface associated with the computingsystem 400. As shown, the computing system 400 causes the display ofvacuum pressure, pump temperature, load amps of the motor, RPM of thevacuum pump, a number of barrels loaded/unloaded (or to beloaded/unloaded) by the motorized pump system and various input buttons(i.e., “AUTO”, “ON”, “OFF”) for triggering selectiveactivation/deactivation of the motorized pump system. The computingsystem 400 also includes a notifier that indicates when the oil level ofthe vacuum pump oil reservoir has reached an unacceptably low level,according to the applicable sensor reading. Displaying combinations ofsensor readings to a user/administrator may make it easier for auser/administrator to ensure that the pump system is operated with duecare, so as to avoid damage to the pump system or other damages causedby improper operation thereof.

In some instances, the computing system 400 is configured to provide anotification on a user/administrator interface in response to detectingthat a sensor reading of one or more sensors of the computer-controlledmotorized pump system has met or exceeded a predetermined thresholdvalue. The notification can take on various forms, such as a visualnotification on a screen, a sound, etc.

As is also shown in FIG. 16 , in some embodiments, a user/administratormay predefine, with the user interface, a number of barrels to bepumped/loaded/unloaded by the presently disclosed motorized pump system.The user may then press the “AUTO” button to provide input foractivating the motorized pump system to pump the predefined amount offluid. The computing system 400 may then automatically deactivate one ormore components of the motorized pump system upon determining that thepredetermined number of barrels (or other volume metric) of fluid hasbeen pumped/processed by the motorized pump system. This functionalitymay reduce the number of costly fluid spills that will occur whentransporting fluids in tank trailers with semi-trucks.

FIG. 17 illustrates an exemplary representation of an administrativecomputer interface (e.g., of a remote system/device 440) incommunication with a computer-controlled PTO driven motorized pumpsystem. In the embodiment shown in FIG. 17 , the administrative computerinterface includes additional functionality and/or features as comparedwith the interface shown in FIG. 16 . FIG. 17 shows that, in someembodiments, an administrator defines threshold values that may triggerthe computing system 400 to selectively deactivate one or morecomponents of the motorized pump system (e.g., the generator or themotor). For instance, the administrator may define a maximum operationalpressure for the vacuum pump or tank (e.g., in PSI, inHg, or otherunits), a maximum operational temperature for the vacuum pump, a maximumstarting load for the motor, and/or a maximum pumping volume or weight(e.g., in barrels or other units). Additionally, the administrativecontrols may allow an administrator to selectively enable and/or disablecertain functionality accessible to an on-site user/semi-truck driveruser interface. For instance, an administrator may disable wirelessoperation of the motorized pump system and/or manualactivation/deactivation of the motorized pump system. To ensure thatonly administrators may access administrative controls, administrativecontrols may include security measures for access/issuing commands, suchas passcodes, biometrics, etc.

In this way, freight company administrators and/or fleet commanders mayensure optimal operation of computer-controlled PTO-drive motorized pumpsystems that extends the economic life of the pump systems.

FIG. 18 illustrates a flowchart illustrating the power managementcapabilities of the computer-controlled power take off (PTO) drivenmotor system 100. In particular, the computing system starts at step 500(which may be operational on controller 208, first controller 210, orthe ECM controller 220). When the diesel engine is not running, thepower to the computing system may be received from a crank battery, anauxiliary battery 209, a solar panel 211, or grid power 213. When thediesel engine is running, power may be supplied from the alternator orfrom the other components mentioned above. At step 502, the computingsystem monitors the electronic components of the computer-controlledpower take off (PTO) driven motor system 100 as well as the diesel truckto determine their status. At step 504, the computing system determineswhether the motor 230 and pump 232 are running (such as by readingcurrent, voltage, or some other indicator). If the motor 230 is running,then at step 506, power is provided to the motor from available sources(e.g., generator 204, auxiliary battery 209, solar panels 211, and/orpower grid 213). Likewise, the computing system determines whether thegenerator 204 is running ate step 508. If the generator 204 is runningand the motor 230 is not running, then, at step 506, energy is directedto the one or more auxiliary batteries 209 to charge them. At step 508,if the voltage of the auxiliary batteries 209 is above a predeterminedthreshold and the motor 230 is not running, then power may be sent fromavailable sources (e.g., auxiliary batteries 209) to other components,such as climate control or other driver conveniences, or back to the PTO202 through the generator 204, all of which increase fuel economy byreducing the mechanical load on the diesel engine. It will beappreciated that a minimum state of charge threshold may be programmedin the computing system to ensure that the auxiliary batteries 209 arenot depleted and may be used for the motor 230 and pump 232 even whenthe semi-truck engine is not running. For example, a predeterminedminimum state of charge may allow sufficient power for the motor 230 andpump 232 to run the average time required to empty the tank 128.Accordingly, at step 510, the system checks if the diesel engine isrunning. If not running, the process returns to 502 and the cyclecontinues. If the diesel engine is running, then at step 512 the stateof charge of the auxiliary batteries 209 is determined. If the state ofcharge is not above a predetermined threshold, then, at step 514, poweris directed to the auxiliary batteries 209 for charging. If the state ofcharge of the auxiliary batteries 209 is above a predetermined thresholdand the diesel engine is running, then at step 516, power may bedirected to the generator 204 and PTO 202 or to other electricalcomponents, such as the climate control system, to thereby increase fueleconomy by reducing the mechanical load on the diesel engine.
